Review on Waveshare Power Over Ethernet HAT (Type D) For Raspberry Pi 3B+/4B 802 by Timothy Hughes

That must be generating a lot of noise on the ethernet port because my speed has dropped a lot, I'm talking about 25-75 kbps on a gigabit connection. My length was well below the Category 6 limit, about 200 feet max. I'm using this in an industrial application so removing them and installing normal power supplies was no easy task, but I learned my lesson from it. I throw six of them in the trash. And yes, this is the "V2" version with a small addition; Instead of fixing the problem, they decided to fix it with this late filter. Still not good enough!
